I love places that openly promote their happy hour deals and welcome happy hour goers. I always saw their big sign out the front of the restaurant for their $5 food and drink happy hour deals and finally gave this place a go - and I highly recommend you do too.
On a Tuesday afternoon at 4:30pm, this place is dead and you'll have your pick of tables including long benches for bigger groups and comfy booths that fit 4-5 people. I was greeted immediately with 'Irasshaimase!' by all of the staff when I walked in, which I haven't heard in a while. We had a great server who regularly came by the table and was great with suggesting food options for five people (the prawns come with five pieces) and could talk knowledgeably about the menu.
My favourite happy hour options were: sake, Tomo's house roll (changes every few days), ramen burgers (messy but delicious), tataki and tuna poke. I also love that they have a decent list of nine $5 food options and beer, wine and sake drink specials too.
Note: Some of their specials are slightly smaller than the normal dishes, which is entirely reasonable. They also happily split our bill! Check the happy hour list out here: http://goroandgun.ca/events.
