I recently ate at Cabo Wabo in Las Vegas. The food and service were OK and the prices were reasonable.
However, you need to be aware of the scam Cabo Wabo will put on you when you're not looking. One of the members of my dining party ordered a $9.00 draft beer off the menu. Ok,...$9 bucks for a beer is high, however it's the Vegas Strip so that was expected.
What wasn't expected was when we got the bill, he was charged $18.00 for his $9.00 beer. We asked about it and the waiter told us the beer is $9.00 and the "commemorative" Cabo Wabo glass was an additional $9.00. WTF! $18.00 bucks for a 22oz beer? Needless to say the $9.00 surcharge was reflected in the waiters tip, since he didn't warn us about that.
Buyer Beware! This is a scam and a rip-off! Also, you're stuck with an unwanted glass that you have to carry around with your when you're walking the Strip.
