For as hyped up as BelAir Cantina was, I wasn't super impressed by any means. I went later on a Friday night, and it was fairly busy still, but we were seated within 5 minutes or so.
The chips and salsa are really good, and the three different salsas are all exceptional, but that's probably the best thing on the menu. I had the nachos and was very unimpressed; the portion was fairly large but the nachos were nothing special and weren't super hot either.
The location and service are great, but I wouldn't say the food is worth the walk or the potential wait on a busy night.
