I don't know where you plan to stay but i will offer you some suggestions. As this is our premier vacation spot several times a year.
For a great breakfast, lunch or dinner try out Steve's Famous Diner. When we arrive in town this is our FIRST stop usually for lunch. I love the eggplant parm. You WILL NOT get a bad meal there. If you see something you like don't worry and order it you will not be dissappointed. Check out the fresh baked HUGE muffins on the counter they make a great snack or lunch. Coffee is excellent here. Meals are not expensive. And they WILL make mickey pancakes upon request.

This resturant is located on atlantic blvd. south. If you come in off Internation Dr dead end at the beach take a right about 1 mile on the right is Steve's it's a not to miss each trip usually our first and last stop. We get breakfast on the way out of town.
Aunt Catfishs is a must. Great fresh seafood here. Travel down atlantic south to Port Orange take a right at the light and cross the bridge it's immediatley on your left. They serve lunch and dinner excellent salad bar and HOT bar with fixings. Never had a bad meal in all the years.
Billy's Tap room- Ohhhhhh man is this a yummy place to eat. It's only open for supper. Been a mainstay in Daytona for like 85 years! So you know it's good! Great Bread on the table, homemade dressings, food is freshly made to order. They are FAMOUS for there crab cakes and if you try them you'll see why. IF you are sick of seafood try the hamburger steak it's homemade and treffic! They also serve other steaks a popular dish is there fish in a bag never tried it but a TON of people are always getting this when we are there. You WILL need ressies' for this place it's draws the locals out in droves. If you are at the dead in on Int' to turn north or south onto atlantic take a left and head north about 5-6 miles you will come to a large stop light look for it there is a mall caddy corner the stop light. Take the left turn here. Travel about a 1/4 mile you will pass an out back on the right but look to your left look HARD or you'll miss it. There is a burgundy canopy out front that will say Billy's tap room. There is a red light there take a left and park street side and walk around front to enter billy's. If you go across the bridge you've passed it.
Julian's- this is an excellent resturant for steaks, seafood ect... They have nightly live piano playing. Family owned resturant. No ressie's needed if you arrive say by 7. It's on the way to Billy's Tap room. Using the same directions before you get to the light to turn right to go to Billy's about 1 mile before the light you'll pass Julians. Look for the red building with a STEEP roof Julians is printed up on the roof.
Bubba Gumps Seafood a must do. Wonderful food, the wait staff will drill you on movie trivia from the movie. Just a FUN place to eat and the food is excellent. Try the huspuppie apptizer EXCELLENT. Also cajun shirmp all the soups are wonderful here. This is located in the Ocean Walk shoppes located n. atlantic blvd. There is a cold stone creamy next door that makes for a tasty dessert and sharing is allowed.
Port Orange STeakHOuse. Best steaks around! Wonderful LOADED baked potatoes. Check the hours they are open for lunch and supper. If you are driving like to aunt catfishes and cross the bridges travel on about another mile or so look for the Kmart shopping plaza on the left you'll be coming up to a stop light it's located on the far side of that plaza. YUMMY!!!!!
Ocean Deck is located on the ocean with a view of the ocean. It's n. atlantic blvd. Great food extended dinner hours i think they are open till two. The best lobster rolls we've ever had. Clam chowder in a bread bowl can't be beat and a yummy mahi mahi!! Will not break your budget.
These are my favorite places in Daytona besides the Krispy Creme.LOL BTW that's on internaional drive coming towards the beachs on the right i suggest you stay in the left lane coming in just in case that HOT sign is ON.LOL

Have a wonderful trip.
