The kitchen at Megalomaniac plates crab-crusted Salmon Oscar under lemon hollandaise and a short rib lacquered in soy and black pepper over jasmine rice — food meant to be ordered as dinner, not grazed between tastings. That is the surprise at this Twenty Valley winery: its Food+Drink program has outgrown the snack board that usually rides along with a cellar. The name was always a wink — John Howard built Megalomaniac as a knowing joke about the ego every winemaker is accused of carrying — and the same maximal streak that gives the bottles their swagger now runs through a menu a table can plan a full meal around, Wednesday through Sunday, brunch to dinner.
The range is what carries it. Past the Salmon Oscar, with its rosemary-garlic potatoes and asparagus, the dinner list runs to an Adobo-Glazed Short Rib finished with crispy garlic, sesame, and chili oil, and a Pistachio-Crust Chicken set over heirloom carrots, roasted garlic labneh, honey, and crushed potato. Lunch turns lighter and looser — a Montreal smoked brisket sandwich on an everything bun, Tajin shrimp tacos under pineapple salsa, a Mega Green Bowl of quinoa-and-chickpea tabbouleh and everything avocado. The shareables keep the old winery-grazing instinct without coasting on it: tuna cones with avocado-wasabi crema, PEI oysters with grapefruit mignonette, a warm pull-apart Bubble Bread heavy with garlic butter. The Lobster Roll, East Coast lobster on buttered brioche, surfaces only on weekends and only in limited numbers.

What to order
Tiers reflect how diners actually talk about each dish — Diamond is the rarest. Tap a dish to cast your vote.
Megalomaniac has enough current menu depth, reservations infrastructure and patio context to read as a restaurant-grade winery stop rather than a tasting room with incidental snacks.
02
John Howard's Niagara Wine Story
The winery has a clear founder narrative around John Howard, Niagara wine and the John Howard Cellars identity, which gives the visit more personality than a generic vineyard meal.
03
Dinner Anchors Beyond the View
Dishes like Salmon Oscar, Adobo-Glazed Short Rib and Pistachio-Crust Chicken give the dining program real order strategy, so the scenery is not doing all the work.

How to eat at Megalomaniac Wines
1
Order Salmon Oscar for the Winery-Dinner Baseline
Use Salmon Oscar as the proof that the Food+Drink room is built for dinner, not just tasting-room grazing. It is the most direct special-occasion main on the menu and the safest order when the table wants one dish to justify the reservation.
2
Share the Charcuterie + Cheese Platter Before the First Pour
The Charcuterie + Cheese Platter is the easiest way to make the visit feel like a winery stop before the mains arrive. It gives the table something shareable and wine-friendly without crowding out dinner orders like Adobo-Glazed Short Rib or Pistachio-Crust Chicken.
3
Use Prix-Fixe Dinner for Salmon Oscar or Short Rib
The prix-fixe dinner signal is the move for guests who do not want to assemble the whole night dish by dish. Build that plan around Salmon Oscar or Adobo-Glazed Short Rib, then use the wine list as the through-line.
4
Take PEI Oysters to the All-Weather Patio
The all-weather patio and vineyard-facing setting are part of the reason to choose Megalomaniac over a standard dining room. PEI Oysters make that room choice feel deliberate: light, wine-friendly and built for a table that wants the view involved from the start.
5
Save Lobster Roll for Weekend Lunch
Lobster Roll makes the most sense when the visit is a weekend lunch or wine-country stop rather than a heavier dinner. Pair it with a lighter shared order like Marinated Olives or PEI Oysters if the table is still planning a tasting around the meal.
