Will you stand in the queue for 40 minutes for a Ham-burger?
Yes, you need to wait that long for a ham-burger from this new shop from Japan. With food quality better than Mac-Donalds but the cost is also 50% higher. I've tried the cheese burger. The beef is much juicer, and other ingredients are also very fresh. Is it worth the wait? Well, it's up to you.
Now a toy RC helicopter can be as cheap as $240. It is very small and light. Work with re-chargeable battery that can fly for 5-10 min after 30 min of charging. Problem is you can never control it precisely.
