Weekend Brunch at O SEA!
Multiple dates availableYou asked...we listened! BRUNCH has arrived at O SEA! Join us every Saturday and Sunday from 10am-3pm for a collection of Orange's favorite breakfast snackies. Think Brioche French Toast 'Tres Leches', Sweet & Smoky Chilaquiles with Salsa Macha, Breakfast BLT Greens, and Cinnamon Buns with Pistachio, Blood Orange, and Green Cardamom. Bevies? The best Mimosa in Old Towne Orange, maybe a Mango Michelada, maybe an Iced Lavender Latte. Whatever floats your boat. Brunch not quite your thing? We serve our regular Lunch menu from 10am-3pm as well. We look forward to serving you!Happy Hour at O Sea - Weekdays from 2-5pm
Multiple dates availableOrange's best Happy Hour is back at O SEA - join us every weekday afternoon (Tuesday-Friday) from 2-5pm for 50% off our entire bottled wine list, $1.45 oysters, and a selection of menu favorites - spicy tuna on crispy rice, salmon ceviche, and a lil cheeseburger - just to name a few. We look forward to serving you!
