We were there a few weeks ago for spring break at lunch. There was a mix up with one of our meals and our very attentive server went above and beyond to fix it and brought us free deserts for our trouble. We placed a few dollars in cash on the table for a tip and left. Our server actually found us just outside the restaurant, and tried to return our tip, explaining that she was not permitted to take it. I then went back into the restaurant and spoke to a manager/lead explaining that this server had gone well beyond the level of service expected and I was not taking back the tip. The manager tried to reason with me but we left and refused to take back the tip... So, no you are not expected to tip at breakfast or lunch.
