Seibel's is a family-style restaurant at Rte 198 and Rte 29 where they have been mixing up their own ice cream since 1939. The ice cream was pretty good. We visited after people mentioned Siebel's in comments on a post about ice cream joints for a summer night.
If you go to Burtonsville, you should also check out the two blocks of restaurants running along Rte 198. That includes kabobs at a branch of Maiwand Kabob, Cuban at Cuba de Ayer, and both coffee and Ethiopian food at Coffee Oromia.
Seibel's Restaurant and Ice Cream
15540 Old Columbia Pike
Burtonsville, MD 20866
(301) 384-5661
NEAR: This is on Rte 198 just west of Rte 29. From Howard County, you take the first exit on Rte 29 south of the river. Go through the traffic circle at the end of the exit. That puts you on an old piece of Rte 29 that passes an Indian temple and a garden center. Turn right on Rte 198 at the traffic light. Seibel's is a block up on the right. There is a sign.
