When I was told Boojum was the place to go for a burrito in Belfast I was at first skeptical. However, after finishing my burrito I must say it was quite good, even as someone from the USA who's used to Chipotle and other Mexican food.
There was a long line on the Friday night going out the door but the wait still wasn't too bad, only took about five minutes or less. I got a vegetarian burrito which is the cheapest and comes with free guacamole and pepper and onions, lime or mexican rice, black or pinto beans, and a variety of salsas, lettuce, and corn. I felt I got a good value and the portions were a good size, definitely not too small. Also the staff were very friendly and helpful.
I'll definitely be coming back as a staple of Belfast!
Cons: Can be long wait
