Does the pesto pasta contain nuts?

Yes, our Pesto uses Walnuts instead of Pine Nuts.

For a nut-free option, I recommend the Marinara or the Alfredo.

RAG Source: Ingredient_Pesto.pdf

I'll take the Alfredo. What wine goes with that?

Excellent choice! A Chardonnay pairs beautifully with the creamy Alfredo sauce.

ORACLE VECTOR SEARCH

Guests have questions. Your waiters are busy.
Our RAG-Powered AI answers questions about allergens, ingredients, and pairings instantly.

It doesn't hallucinate. It queries your actual PolicyDocument and Recipe tables using SQL Server 2025 Vectors to provide accurate, safe answers.

REAL-TIME ARCHITECTURE

How an order gets from a phone to the grill in milliseconds.

1. API Command: CreateOrder splits items into Station Tickets.
2. SignalR Push: Tickets are multicast to specific Station Groups (Grill, Fry).
3. Bump Logic: Cook taps "Done". Expo screen updates. Guest gets notification.

OrderRoutingService.cs

public async Task RouteOrderAsync(Order order)

{

// Split by Station Logic

var tickets = _router.SplitByStation(order.Items);

foreach (var t in tickets)

{

// Real-Time Push to Kitchen Screens

await _hub.SendToGroupAsync(

t.StationId, "NewTicket", t);

}
