My car runs cool on the interstate, but in-town driving it begins to run hot according to temp guage. I open the coolant reservoir to replenish water and it sucks what water is in there out when top is taken off. It bubbles out of reservoir while car is running with top off as well. Could this be the thermostat or a fan issue?

This would be the thermostat.

Could be...how much coolent are you loosing? Are the fans running when the engine is warmed up? If you are loosing a fair amount of coolant it's probably either a leak somewhere or a head gasket . I would check carefully for any leaks, paying attention to the water pump, radiator, hoses, and along the head gasket area on the back of the motor...these usually fail more toward the driver's side/rear. Also check for white smoke in the exhaust, foam/coolant in the oil, and air bubbles coming out of the coolant (all signs of head gasket failure). Water bubbling out is normal if the engine is getting too hot...air bubbles never are. If you're not loosing a lot of coolant and the fans are working, then the thermostat and new radiator cap would be the best place to start.

Radiator cooling fan is NOT running at all car runs fine on interstate air is being forced across radiator while car is moving letting it cool the Coolant down. But while in town or Heavy traffic airflow is restricted to what ever it gets nothing is being pulled across the Radiator to cool the coolant down.
check and see if you fans are running with the Ac on if they are you relay is bad if not, look for a bad fan motor.

sounds like you might have an air bubble in the system. Check to see if you have a bleeder valve next to the thermostat. If you do then try opening the valve till fluid comes out then close it down and you should be fine

you got air in the system more than likely most resevior systems are there if the outlet on the engine is higher than the radiator gravity takes effect and bleading the system allows all the trapped air out of the system should be a bleaded screw around thermostat housing

MOST LIKELY IT WILL BE THE COOLING FAN IS NOT WORKING.
TRY FINDING AN INDEPENDENT SHOP INSTEAD OF THE DEALER OR A CHAIN STORE BECAUSE YOU WILL BE OVERALL MORE PLEASED WITH THE FINDINGS AND THE SERVICE.
LEAVE IT THERE WITH THEM SO THAT THEY CAN FIND THE PROBLEM FOR YOU, IT WILL BE A LOT BETTER THAN JUST REPLACING PART AFTER PART AND NOT DOING ANY GOOD.

Sounds like a fan problem.
