While travelling I specifically try to avoid restaurants with large menus. Why? Because they make me miserable.
First, you spend endless time just browsing through the menu, looking for the best dish (whatever that means anyway), comparing each and every option, and struggling to decide. Then, just after you found something to order, the dish is either not available or right after ordering, the neighbouring table has found an even more delicious meal. You wouldn't be happy with yours anyway. You're welcome.
Logic suggests that having options allows people to select precisely what makes them happiest. But as studies show, abundant choice often makes for misery. This holds true for websites as well.
