Discovered this restaurant thanks to the recommendation of a friend. Its centrally located (between leicester square, covent garder and trafalgar square) so very convenient if you're looking for a restaurant in central london. However its popularity (and the fact they don't take reservations) means you're virtually guaranteed a wait. The friendly staff will however add you to the waiting list, and give you an idea of the wait, so you can get a drink nearby and come back when your table is ready. Alternatively you can wait at the bar for your table. We waited 45 minutes, but it was worth it. We chose the street food option, a selection of small dishes (tacos, tostadas, quesodillas etc) that you can share. they recommend 2-3 dishes per person, which is very reasonable with an average prie of only £3 per dish. With prices like this, you can understand why this place is always packed. the food itself was delicious, but a word of warning, avoid the red chili sauce, I tried a tiny amount I thought my mouth would explode!
