I am here to tell you that Restaurant.com does exist. Yes, Virginia, there is such thing as a (nearly) free lunch. For example, you can score a meal on a weekday at Saito, 249 Railroad Ave. for $23 less than you’d ordinarily spend. Though the site says $10 for a $25 Dining Certificate, if you insert the Discount Code “BITE” at checkout and hit apply, your cost comes out to only $2. A few days ago, I went a bit slaphappy, buying and printing out certificates that I plan to use through the winter and spring. Result? $200 worth of gift certificates – eight different restaurants – for which I’d paid $16. TOTAL. Now THAT’s a great Onthecheap tip!
