An honest-to-God great, authentic Mexican joint in England. I didn't think it was possible, but El Burrito is it. Get the chicken tinga w/ habanero salsa...
Different to the more 'commercial' burrito places, very authentic here. Best burrito in town in my opinion, and best price. You get a drink and tacos with your burrito
You can buy proper white corn tortilla here. Comes in a vacuum pack. No need to compromise with that flour tortilla disguised as "corn" tortilla at Tesco/Sainsbury.
You get a nice and sizeable burrito for your money here. Chicken Tinga with Habanero Salsa is recommended - nice balance between spicy and tangy. Agua fresca is mediocre, though.
