Mar 23, 2025 · Jesse GuyettThis is a long overdue review! We've been coming here for years. We have had graduations, birthdays, anniversaries dinner here, small parties and larger parties and Sumo Sushi, hands down, has been the best! We have tried many local sushi spots and Sumo Sushi is our favorite. We appreciate the all-you-can-eat and love how fresh their fish is, their rolls are delicious and their appetizers are enticing! Our favorite Sushi rolls are the salmon delight and salmon ceviche. Our regular appetizers are the spicy garlic edamame, baked mussels and we some times do miso as well. Their service has always been friendly and attentive, making our experience enjoyable. The atmosphere is clean, open and has a fun vibe with tasteful music. Our food comes out on a timely manner and like I mentioned we have been coming here for years and have had great experiences during both lunch and dinner, weekdays and weekends! Must visit if you are a sushi lover!
