At Alternate Grounds Dockside, the water gets a vote before the menu does. The restaurant sits on the Sarnia Bay marina, a Canadian restaurant and bar set up so the patio and the boat basin are part of the meal instead of a view glanced at between courses — the kind of place a table picks for the setting first and sorts out the order second. When the order comes, it is built wide to match the draw: weekend brunch, tacos, seafood, pasta, wings and comfort-food mains, all kept at the easy register of a Bay-side afternoon, where lunch and dinner blur into one unhurried sitting.
Seafood is the menu's strongest thread, and the Lobster Roll is its clearest expression — creamy lobster heaped on a garlic-butter grilled hoagie with a little greenery and a spoon of pico, the dish that bridges the marina and the kitchen in one handheld. It runs deeper than the roll. Lobster Mac and Cheese, Fish Tacos, Crab Cakes and a straight-ahead Fish and Fries give the dockside theme real weight. Around it sits a taco section that does most of the menu's wandering — Hot Honey Shrimp, Carne Asada, Jerk Chicken — next to handhelds like the Crispy Gochujang Chicken, fried chicken lacquered in honey gochujang with house-made kimchi, cucumber and sriracha mayo. The casual side fills out fast from there: the Buffalo, a Reuben, Jumbo Wings, a Caribbean Cobb and a Picking Platter built for sharing. And the kitchen still lists the wanderers — Pad Thai, Florentine Mac and Cheese, Falafel and General Tsao Cauliflower — so a table of mixed appetites rarely runs short on routes.

How to eat at Alternate Grounds Dockside
1
Order the Lobster Roll First
If the visit is about the water, start with the Lobster Roll. It is the most direct bridge between the marina setting and the menu: creamy lobster, garlic-butter hoagie, greens, and Pico de Gallo without needing a full seafood dinner.
2
Make Brunch the Jerk Chicken Huevos Run
Weekend brunch is where Dockside gets more specific than a standard patio grill. Jerk Chicken Huevos, Lobster Latke Benny, and Chicken and Waffles give the daytime menu enough identity to justify choosing morning or early afternoon service.
3
Split Tacos Before the Pasta Course
For a table that wants range, use the taco section as the opening move before bigger plates. Fish Tacos, Hot Honey Shrimp Tacos, Carne Asada Tacos, and Jerk Chicken Tacos let the group sample Dockside's sharper flavours without committing everyone to one main.
4
Add Crispy Gochujang Chicken for Heat
The menu has plenty of familiar comfort-food routes, so the Crispy Gochujang Chicken is the useful counterweight. Honey gochujang, house-made kimchi, cucumbers, and sriracha mayo give the handheld a brighter edge than the Reuben or Buffalo chicken sandwich.
5
Let the Waterfront Patio Set the Pace
Treat the patio as part of the meal rather than just a seat choice. A Lobster Roll, Fish Tacos, Jumbo Wings, or Caribbean Cobb Salad fits the Sarnia Bay setting better than overbuilding the table, especially when the room is being used for a relaxed marina stop.
