We've been coming here for many years and love Hnoi and the Vegan Joint. Since they remodeled and expanded, it's also been a great place to hold meetups, and meet with larger groups. The food has always been decent, and the prices very reasonable. In fact, I don't believe they've raised their prices in many years, and the current menu prices are still lower than nearly all the other Thai places. I usually order a lentil or black bean burger (only $5.95 and comes with a choice of regular or sweet potato fries), though their Thai dishes are also alright. Food isn't gourmet, nor will it likely blow you away, but it's consistently good, and the vibe is great. They bring in desserts from No Udder and a bunch of others, so your sweet tooth will always be taken care of as well. For what it's made to be, this place is awesome in my view.
It's also a very convenient location, just a minute off the 10 freeway at Overland.
