Takeout/delivery vs. sit-down menu
I'd like to get a few opinions from those of you with brick and mortar restaurants.
I'm having a discussion with a friend about a restaurant menu, where certain items can only be eaten in-house, no takeout or delivery (restaurant has both normally). In other words, there is a takeout/delivery menu, and a sit down menu. Both are almost identical but for one or two items that they won't let you take out or deliver to you. The items are not complicated or messy, and could be easily packaged for takeout/delivery.
I'm leaning towards why would a restaurant restrict them from takeout when they're a popular item, which might put some people off and send them somewhere else, and my friend is adamant that it's a better idea for them to not offer them for takeout/delivery to get people to stick around.
I wanted to get some input from those of you who have experience with this, just to get a clearer picture of the pros and cons of doing that, and which way might work best, if there even is a "best" way.
