It is relatively well priced, well-presented, and in a convenient location.
Food is good, and as I remember, free ice cream.
It didn’t really stand out in my mind, however.

Notable Mexican restaurants in Tyler (some of the best in Texas, IMHO), in order of price (though not necessarily value):

Pico de Gallo
Don Juan’s (on the square)
Taqueria El Lugar (on Golden Road)

All of these offer authentic and innovative dishes, great atmosphere, and good service.
