Its not-free-anymore Observatory is absolutely worth a visit! The views of the Tokyo Tower 🗼 and the city are amazing. Even Mt Fuji 🗻 is visible when the weather conditions allow for it. Now, the options for entering the Observatory on the 33rd floor are the following:

• Eating at "Dining 33" restaurant (quite expensive)
• Getting a drink at "Skyroom Café & Bar" (you need to pay an additional 500¥ admission fee and queue to order - there was a pretty long queue when we went)
• Ordering take-out desserts at the "Dinner 33 Pâtisserie à la Maison" - which we opted for. The desserts were not cheap surely (850-1200¥ the piece), but they were delicious and maybe even cheaper than option 2. They cannot be eaten at the Observatory or anywhere around the 33rd floor (we went down to Lobby B1, ate them and up again where we showed the invoice and we were granted access).
