Place used to be decent but service has gone downhill to the point of unbearable. The third time we've been there in 6 weeks and the service has continued to be slow. Staff is nice, but inattentive due to regularly being understaffed. Tonight, had a reservation for 13, arrived on time to a half empty restuarant...took 20 min to get a drink. Spoke to manager who apologized/said situation would be addressed. Took order and food didn't come out for over an hour. On top of that , forgot two of the orders. Manager never came over. When the bill came, they didn't credit / take off a dime. From a customer service / business standpoint, just a total whiff. Will never go back. I'm actually just embarrassed for them more than actually upset.
