We're regular here ever since we came here with a Groupon couple of years ago. Now we visit here once every couple of weeks.
The service is warm, and the food good. Their lunch specials are pretty good too.
Not sure why the negative reviews, I guess you can't please 'em all..
P.S.: Those with Groupon and complaining..The Groupon amount is deducted after taxes. If an institution is doing it pre-tax, that's nice of them. Most don't!
And, please tip based on the final pre-discount, not the post-discount amount. It's demeaning to the employees, and embarrassing when we are seated next to you.
