Eating restaurant food! 5 weeks!

Tonight, my family and I went out to dinner at a Mexican seafood restaurant. I ate saltine crackers for the first time , in hot sauce. Delicious! Then I had seafood broth (very spicy, but good). I finished up with a shrimp ****tail. My question is : Is this normal for 5 weeks?! I was full, but not in pain. It is the most I have eaten since the surgery. For lunch, my hubby brought me Chinese hot and sour soup with tofu. I ate a bowl full. I know I have not been eating this last week, but the scale at the doc's office said I am still losing (although very slowly). What do you think? PS. It sure tasted better than protein shakes!!!
