We have done many concierge lunches. It's basically the same menu but varies on who the chef is for quality. All have been good to great. How many eat there varies depending on how many BTBs and Zeniths there are and that can be from 20 to 100 plus. I never waited more than 5 minutes to be seated. It is a lot less hassle than the buffet. If you are in a hurry tell the waiter and get a table for 2. My last two E cruises it was in Cypress. We were BTB each time. Last time on the Ascent it did not start until 1230pm, before that it was 1130am. I like the 1230 start time. It gives you more time to get to room and have a drink somewhere. Try it once, you are paying for it.
