Good for you tracking your cash flow, I've heard my friends comment on this too, but they did not do what you did and begin to monitor it. Since January arrived I have been more cautious with money.
Here's what we do to make eating out more friendly to our bank account. We use Groupon to get deals, subscribe to emails that give you perks:
Ruby Tuesdays, BOGO's, also they have promo's weekly
TGI Fridays has $5 cheeseburgers and ff, on Tues only
Panera-kickback gift cards buy $50 and get $10 back, they also give rewards for visits.
Red Lobster, earn points for free appetizers or dessert, they have M-TH daily specials, Mon is unlimited shrimp.
Wendy's-BK-Popeyes-all have apps and promo's
These are just a few of the what's out there if you want to eat out on a budget. Plus if you want to put a snack and a drink in a car, that's another way too.
