Does the Premium plan's cost actually compare well to the revenue from calls it answers?

Yes, and the comparison is worth running with your restaurant's actual numbers rather than assuming. Premium is $99/month for 150 included calls, which works out to $0.66 per call if you use the full allotment, and $1 per call beyond that. Against that, weigh what a typical answered call is worth: even if only 20-30% of your restaurant's calls convert to a booking, order, or catering lead, a reasonable estimate, since a meaningful share of restaurant calls are hours or parking questions that don't directly convert, and the average value of a converting call is $50-100 blending takeout and reservation calls together, 150 calls a month converting at that rate is still several thousand dollars in revenue touched by calls Voksha answered.

The comparison that actually matters isn't $99 versus zero, it's $99 versus what you're currently losing. If your restaurant already answers most calls during normal hours with staff, Voksha's incremental value is concentrated in the calls staff can't get to, rush-hour overflow and after-hours, which is a smaller slice of total calls but a high-value one since those are disproportionately the calls that go to a competitor instead of your voicemail. Restaurants that see the clearest ROI are ones that were previously losing a measurable number of calls a week, not ones that already had zero missed calls, which is rare in a business with dinner rushes and no overnight staff.
