Restaurant gift cards - $25 is an ok amount for places like Red Robin. Just like those $10 Mc Donald's gift cards are a good amount for fast food. Really depends on the eating establishment. Just a tip about restaurant gift cards. The waiter (or cashier) cannot add a tip to the gift card. So if the gift card equals more than the bill, you still need cash on the side to leave a tip. So if you have a $100 GC, but the bill is only $75, then $75 will be deducted from your gift card, leaving you $25. But no way to tip unless you have cash. So it's actually better to give a gift card with an amount that's a bit lower than what someone would spend. That they the remainder can go on their credit or debit card, and then they will be able to leave a tip.
DH and I have gotten $25 GCs to Red Robin in the past. Our bill usually spikes around $35. So our waiter will charge the remaining $10 to our debit card, and then we're able to leave a tip. I love getting gift cards! I got a $75 gift card to the mall for Christmas! Can't wait to go shopping!!
