Ryan and I tried this a few weeks ago and it was really fun! Keep in mind when you visit the restaurant you will be required to purchase $35 worth of food. "Well, if we have to" we said;) We got an appetizer, Ryan got a drink, we each ordered higher-priced entrees, and we also got dessert. Wow. Our total was just about $36, so minus the $25 GC (and plus the $2 to buy the GC), we got waaaay too much food for $13.
The coupon also states that 18% gratuity will be added to the pre-discounted bill amount, although they didn't actually add it in when we visited. Still, a great night for under $20...and lots of left overs:)
There are other restaurants you can order gift certificates to as well, but each has it's own special requirements. This one seemed like the best one to me-- the code is good through May 31st.
