Los Juniors in Vista. Best hole in the wall Mexican restaurant I've ever been to. Everything I've had there is delicious but their adobada is especially fantastic. Their cabeza is as well, but that one doesn't seem to be as popular. The part of town its in has a reputation for sketchiness but tbh I just think the people who say that see Mexicans and automatically think gangbangers.
Sue Thai Om, formerly known as Happy Chang's, makes some excellent Thai food. I was talking to some people who were also waiting for food visiting from Thailand that say it's better than the food in their country. If any of you stop by this one, hmu and I'll walk on down, I could go for it any time of day that my budget allows.
Sublime Ale House has a 12/10 beer selection and hands down the best burgers ever made. They have a fancy mac and cheese that's pretty popular too. Pricy though, so I don't go as often as I'd like.
