Seems to me like it would depend on the date. I would think it would be best to probably notify her before hand give her some choices. Maybe tell her hey you wanna to weiner schnitzel? i have this 35 cent coupon, or hey I know its expensive, but i would really like to take you out to this great steakhouse and i was able to find this 2 for 1 coupon.
She probably wouldnt be to fond of the weiner snitchel idea, but im sure she would be fine with the steakhouse. This question is also probably age/financial status dependent also. Im sure most any college girl would be happy with going to a nice restaurant and using a coupon just let them know before hand or give them the choice.
