Tokyo Skytree is located in old-school Sumida. The 634 meter structure can be seen from all parts of eastern Tokyo but is most impressive up close. Skytree is surrounded by Solamachi, a shopping mall with souvenirs and a food court. Solamachi can get quite crowded on the weekends. It will be much calmer and less touristy to explore around Oshiage and Sumida outside Skytree town, to grab a cheaper bite to eat with the same view of the tower.
Sekai Cafe
Located just a few minutes walk from the tower, Sekai Cafe is a quaint cafe that focuses on natural, plant-based foods. Their staff is bilingual and the menu is offered in English. While meat is served, vegetarian options are their main speciality. A rarity in Tokyo, the vegetarian dishes have a variety of seasonal vegetables and is normally served with a soy meat. 
Their daily menu changes on rotation. The vegetarian curry is a popular item. The curry is spicy for being Japanese-style, a sort of fusion between Indian and Japanese curry. Seasonal vegetables and white rice round out the dish for a filling meal. Drink sets are also offered for 200 JPY extra. Their lunches are also offered for take out. On a nice day, visitors can grab a vegetarian bento and a bench next to the river and relax under the large tower. The cafe is spacious, with single and table seating, with outlets and wi-fi available. 
Sekai Cafe is open from 7:30AM to 6PM and is closed on Tuesdays. Their daily specials start from 1,000 JPY.
