We bought the BLT @ Ballys coupon but my wife wanted lobster (>$58 limit) so we asked them about that. They told us to get the more expensive coupon, I think $118 for $218 or something, and we did and everything was great. Terrific service and food.
Travelzoo has some great deals at places that are generally higher-end than some of the other coupon sources. However they tend to have more fine print limitations, e.g. not valid on weekends/holidays and/or early expiration dates. So I suggest not buying it until you are sure you can use it and after you have made a reservation. I learned this the hard way: I once gave my wife a spa coupon and it expired before she had a chance to use it.
Also some of those places are very expensive without the coupon so keep that in mind when tipping. I got a massage at the Hard Rock using the coupon and the suggested gratuity was $30 which was more than I had in my pocket.
