KEY POINTS

If I've approached my table multiple times already about ordering to no avail, and I need them to start making some decisions (maybe I need the table or I'm about be get busy with a party), what's one thing I can do?
Approach and offer recommendations.
"Can I offer you some recommendations here?"

When re-approaching and table is asking specific questions about a dish, you can just answer. With more general questions, however, offering recommendations may be appropriate.
If they have no questions, that typically means they're ready to order.
