I've been to Showmars a couple of times during my lunch break with co-workers. It's casual, reasonably priced, offers good food, and the service is very quick. No sooner than we've ordered at the counter and sat down, someone's bringing our food out to us.
I usually always order the gyro ("yee-roh") pita sandwich. Why? I'm at a Greek-owned restaurant. Of course I'm going to go with one of their specialties! Plus, few places offer gyros...and I LOVE 'em! I just try not to think of the lambs that were slaughtered so I could enjoy them rolled up in a tasty pita, dripping with tzatziki cucumber sauce. The fries that accompany the pita are always very flavorful, too. They're not your average french fry; they have a little spice to them.
My co-worker always orders the fish sandwich. Why? The menu says it's the "best fried fish filet sandwich" and he swears by it. Go figure.
