Personally I think $16.00 is even a difficult break even point for B & C. We paid $14.50 and just broke even with them. The most expensive lunch menu item is $8.99 and the sundaes run about $6.99. That's if you can even get a sundae down after having lunch, we just usually grabbed a milkshake for $3.99. It really wasn't worth us buying them this time. When we paid $10 or $11 for them it was a better deal. I know tip is included in the cost of the voucher, but we always leave a tip anyways because they are ALWAYS so good to us and we pay cash for DS meals.
Now when we use them at the Pepper Market we did come out ahead. DH had a Prime Rib dinner for $18.99 plus, drink and a $3 dessert, I had shrimp fajitas for $15.99, plus drink and dessert. We did well here.
All in all, they just aren't the deal they used to be. You will be very lucky to break even anywhere other than the two places mentioned above when buying them for $14, but I dont' think you'll come close when paying $16.
