Oddly, I took a look at that date for anywhere from 2 to 5 guests and there were plenty of times available. When you select 6, it drops to the one spot. I'd call them and book that way.I tried making reservations for 6 at Cowfish for 10/30 today and the only thing showing was 9:45 PM! Are walk-ups more likely to happen for a party of 6? I just don't know what to expect at this point!
