I stopped by here on the way to the Imperial Citadel of Thang Long after seeing the Ho Chi Minh Mausoleum and the One Pillar Pagoda. The cafe inside was modern, and the terrace seating on the second floor was really nice and pleasant. When your food is ready, they give you a numbered ticket with an alarm that rings to let you know it's time to pick it up. There aren't many cafes along the way, so I highly recommend this spot if you're planning a similar route and need a place to take a break.
