Reviews Summary

Mama D's Cafe Mercantile is a beloved local spot praised for its delicious breakfast classics and warm, inviting atmosphere. While many rave about the waffles, omelets, and baked goods, some diners have noted the potential for long waits and the cafe being uncomfortably hot during peak summer months. The cash-only policy is also a key point for visitors to be aware of.

"Amazing spot right in town in Booth Bay. If you’re looking for a nice diner style breakfast/brunch vision but with a cozy homey vibe, this is the place for you. I felt a bit naughty so went for the vanilla iced latte, wife was bold per usual with a mimosa. She’s on holiday so who can blame her?
Moving to the food - she got the daily special ciabatta with Canadian bacon egg tomato and cheese. Stole a bite against her wishes and it was worth the potential wrath I could face when we touch down back in Chicago. I went for the custom omelette - spinach, onion, cheddar, sausage. Real savvy veteran stuff. Waitress had great personality - even called us her darlings. Cheers to Mama D!"

"Very popular local place. Cash only. Good variety of breakfast foods. Everyone enjoyed their meals. The Belgian waffles were great!

Of note, we went during the heat of summer, and it was sweating hot inside. Many people were fanning themselves with menus. I can't imagine what it felt like in the kitchen!"

Josh Pagano

"Everything we had here was amazing! Especially the waitress who posed for my picture!

We loved the decor though-out.

The waffles were the best, super soft and fluffy! I was really just a perfect breakfast. Pleasing two teens is hard and Mama D’s did it!"

On the way in to the Topside Inn, we picked up sandwiches at Mama D’s Cafe, a homey place for breakfast and lunch. There’s also a great local coffee shop, Moosehead Coffee and Ice Cream, located across from the post office. That evening we ambled from the Topside to the Boat House Bistro Tapas Bar and Restaurant, where the twins and I sat at the terrace bar on top of the multistory downtown establishment.
