Just returned from my first experience at Teocali (25th and Holmes near UMKC Dental School) and really enjoyed it.
I ate alone, so I sat at the bar and enjoyed a margarita (oops...but maybe ok since it's Friday) :) and a beef burrito spread topped with white jalapeno cheese.
The man next to me ordered the fish tacos, which I now wish I would have tried. Other menu items that peaked my interest were the sopes, torta ahogada and upon a friend's recco, pork nachos.
One downside to the place is the lack of chips & salsa service - it's $1.99 (which isn't bad) if you'd like some pre-meal.
A good lunch (and I'm sure dinner) spot on Hospital Hill near Crossroads area for those of you who are in the mood.
