The first time we came to Gen, Luke was our server and he was fantastic! Not only the food, but Luke's service drew us back to Gen. Not even a week apart, my boyfriend and I came back and this time Sam was our server. And his service was terrible. He was no where to be found when we needed to order more food. We asked two different servers to find Sam and 20 minutes later, still nowhere to be found. We had to go up to the hostess to pay our bill. We still tipped him $5, but he definitely did not deserve it. So you're welcome Sam.
Overall, I would recommend the food at Gen. However, if your server is Sam, I'd ask for a different one.
