Mission Burrito

Mission Burrito spiced up Oxford's lunch scene considerably when it hit St Michael's Street a few years ago. Bringing a taste of Mexico to the city centre, Mission's offer of burritos and tacos has proven so popular that they've now opened a second branch on King Edward Street.

Taking advantage of a Groupon offer, it was this new branch I visited on a Saturday lunchtime. With more space for diners than the original shop, customers hoping to eat in should perhaps head here instead. The menu is the same at both locations though, with vegetarian, chicken or carnitas (pork) burritos all costing £5.45 and steak numbers weighing in at £5.95. Tacos with the same fillings are also available, as well as burrito bowls for wheat-dodgers.

I opted for a vegetarian burrito: a flour tortilla packed with rice, black beans, sauteed onions and peppers, lettuce and my choice of 4 sauces, ranging from the mild pico de gallo to more firey options. I played it safe with the medium-spiced salsa verde, skipped the sour cream on offer and added some guacamole into the mix (70p extra). M chose a carnitas burrito with all the extras. As the Great British sunshine was putting in a rare appearance, we decided on an al fresco lunch instead of eating in. The friendly staff presented us with two very sizeable packages: Mission's burritos certainly aren't suitable for those looking for a light luncheon.

The combination of rice, beans and sauteed vegetables was a tasty one, although I couldn't help but wish there had been a few different veggies lurking in there to add more variety (perhaps this would be straying away from the path of authenticity, though). The salsa was on the mild side of medium, so if you like it spicy then be brave and try one of the hot sauces. It was definitely a satisfying lunch: the flour tortilla was stuffed with ingredients, but so expertly-assembled that it didn't prove messy to eat - perfect picnic food. M rated the carnitas option highly: she reported that the marinated pork was succulently moist with a good depth of flavour.

If you're looking for a lunchtime change from the usual panini or salad options, give Mission Burrito a go: its generous portions make its meals good value. Just make sure to bring your appetite.

Verdict: 7/10

Mission Burrito is at 8 St Michael's Street and 2 King Edward Street, Oxford.

Atomic Burger

Behind a white picket fence on Cowley Road, there lies a pocket-sized restaurant serving big burgers. Open the gate, step inside and you'll see that this is no ordinary American diner: under a canopy of dangling superheroes, friendly staff weave between the packed tables, delivering quirkily-named platefuls to hungry customers. Welcome to Atomic Burger, a future Oxford institution.

Although the sci-fi themed burger bar only opened around eighteen months ago, it has already made its mark on the city's dining scene, becoming so popular that booking's even advisable on a school night. It's easy to see why: if the fun atmosphere and 80s nostalgia aren't reason enough, the tasty grub should win you round. Recently revamped, the new menu offers 22 different burgers with toppings to suit all tastes, from the plain and simple Forrest Gump (£6.75), to the spicy Johnny Cash (served with refried beans, hot sauce, American cheese and jalapenos, £8.75), to the freestyle - creative types can dream up their own burger toppings. Unlike most restaurants of its ilk, Atomic Burger gives diners the choice of making each burger on the menu beef, chicken or vegetarian; with veggies able to swap any meaty toppings for a flesh-free substitute. The chatty, knowledgeable staff will be happy to talk you through the options and advise doubtful diners. Should you be tempted to stray away from the burger path, hot dogs, ribs, salad and a pulled pork sandwich are also available, with milkshakes and soda floats rounding off the all-American offer.

Veggie Smokey & the Bandit with sci fries

I used to be a definite Forrest Gump girl, but this week I branched out in the name of research, opting for a vegetarian Smokey & the Bandit (cajun rub burger with grated cheddar, BBQ sauce and an onion ring, £8.95) with a side of garlic and chilli sci fries (included). With a smokey, subtle spicy taste and the gooey addition of the melted cheese, it was definitely a much tastier choice than the sometimes insipid vegetarian offerings at most burger bars. The sci fries were an ideal complement, adding an extra kick - spice lovers will be in their element.

Chicken Jake & Elwood with caesar salad

Atomic Burger's portions are generous and the ingredients good quality: my companion L even complimented their 'nice baps'. She tucked into a chicken Jake & Elwood (served with blue cheese, bacon and mushrooms, £8.75) with a mini caesar salad, while after much deliberation A plumped for a beef Fat Tony (with meatballs, pizza sauce and American cheese, £8.95). A short while later, with empty plates and full stomachs, we all admitted we'd probably be incapable of tackling Atomic's Godzilla Challenge, a man versus food gaunlet which requires brave (or foolhardy) participants to devour a triple burger with triple cheese, firey Godzilla sauce and triple chilli fries in one hour. One name on the mirrored wall of fame had accomplished this feat in an astounding 7 minutes.

Brownie Sundae

If you can make room for afters (unlikely after a Godzilla Challenge, but who knows), Atomic offers American-style desserts such as a pie of the week, waffles and our tasty choice of Finger-a-Fudge Brownie Sundae, a chocolate brownie served with vanilla ice cream, caramel sauce, cream and a fudge finger. Other sweet treats appear on the new breakfast menu (available daily from 10-12), with offerings such as the Snoopy & Woodstock Pancakes (blueberry or chocolate pancakes served with maple syrup and butter, £5.45) sure to tempt me through the little white gate again before long.

As Atomic Burger says, 'great burgers ain't rocket science'. That may be true, but they're certainly a welcome addition to Oxford. And with the restaurant's popularity only likely to increase with the introduction of the fun sticker book loyalty scheme, long may Atomic's reign over the Cowley Road continue.

Verdict: 9/10

Atomic Burger is at 96 Cowley Road, Oxford OX4 1JE. Tel: 01865 790855. Booking recommended.
