I completely agree with the review earlier today. This is not a place for large groups. Our groups experience is eerily similar. We (group of 10) came to 'C'est what?' this evening at 7pm to celebrate a coworker's achievement. The hostess (short redish hair) was very unaccommodating toward our large group and answered our questions with a bad attitude. As the 11th and 12th member of our group joined the party, the hostess insisted that they sit at a separate table. She refused to even let them turn their chairs toward us. She said "you can sit here or you can leave".
In stark contrast, Jeff our server is awesome and came to check on us regularly. He had great recommendations on food and drinks.
