Went on a Monday night and the place was practically empty - we were there about 90 minutes and including us there were only three tables seated at any one time and only five in total. I expected it to be slow, but not dead. At least the service was decent as there was no way the wouldn't be able to keep up.
You expect a good Caesar at an Italian restaurant - not so much at Mirto. No romaine lettuce and only a passable dressing. The cheese was pre-grated. It was disappointing. Next up was the rigatoni - extremely salty! I like salty, but this was too much. Next was the chicken which was pretty good. Desert was good.
Decor is nice, but run down. Presentation of the food was very good. Looks like they're struggling and cutting corners where they think nobody will notice. Decent value with the Groupon, but won't be going back - Mercato down the street is a better bet.
