We have eaten at the two RM locations in Manhattan on several occasions, and enjoyed our meals.
Last night our party of four tried the Hackensack location:
Guacamole: very good
Everything else: poor
Service: agonizingly slow
Music: too loud
Decor: very nice
Cost: $140 with only two glasses of wine - ouch
When we want Mexican we'll stick with El Bandito in Spring Valley NY.
